Nobel Prize for Chemistry 2019
  • The 2019 Nobel Prize for Chemistry is given to three scientists Stanley Whittingham, John Goodenough and Akira Yoshino.
  • The three scientists have been jointly awarded the coveted prize for their development of lithium-ion batteries.
  • They laid the foundation of a wireless and fossil-fuel-free society, taking a step for making a rechargeable world.
  • John Goodenough (from University of Texas) is the oldest laureate ever awarded a Nobel Prize.
  • The foundation of the lithium-ion battery was laid during the oil crisis in the 1970s.
  • Stanley Whittingham started to research superconductors and discovered an extremely energy-rich material made from titanium disulphide having far greater potential.
  • John Goodenough replaced the cathode in the Lithium-ion battery made of metal sulphide by using a metal oxide to make more powerful batteries.
  • Akira Yoshino created the first commercially viable lithium-ion battery in 1985. He used petroleum coke, instead of reactive lithium in the anode, that resulted in a battery that could be charged hundreds of times before its performance deteriorated.
